Description

Technical Field

[0001] This utility model relates to the field of feeding attachments, specifically a feeding attachment for spreading snow melt. Background Technology

[0002] The existing snow melting and spreading work mainly involves installing a feeding device containing snow melting agent onto a vehicle for snow melting and spreading. There are two main types of snow melting agents: one is an organic snow melting agent with potassium acetate as the main component, and the other is an inorganic snow melting agent with "chloride salts" as the main component, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc., commonly known as "de-icing salt".

[0003] However, after the feeding attachment has been working for a long time, the de-icing agent is prone to clump and accumulate in its feeding port, making it difficult for the de-icing agent to be discharged from the feeding port or even blocking the feeding port during snow melting and spreading. In addition, after the feeding attachment has been stopped for a certain period of time, its feeding port is also prone to be blocked by the de-icing agent and cannot feed, requiring manual cleaning before it can continue to work. All of these will affect the effect and efficiency of snow melting and spreading.

[0004] The research objective of this utility model is to design a feeding attachment for snow melting and spreading, which addresses the problems existing in the prior art. Utility Model Content

[0005] This invention provides a feeding attachment for snow melting and spreading, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A feeding attachment for spreading snow melt includes:

[0008] A housing with an installation port at the bottom, and a receiving cavity inside the housing;

[0009] The rotating component rotates to correspond to the inner side of the mounting port and is driven to rotate by a rotation drive device. The outer wall of the rotating component is provided with a number of spaced pushers.

[0010] The material blocking mechanism includes a material blocking member clamped by a first pressure plate on one side of the outer wall of the housing and corresponding to the side of the mounting opening. The lower end of the material blocking member protrudes from the first pressure plate to form a material blocking part that flexibly abuts against the outer wall of the rotating part.

[0011] A sealing mechanism is used to flexibly seal the other side of the mounting opening; when the rotating member rotates to the point where several of the pushing members push open the material blocking part, several material feeding gaps are formed between the rotating member and the material blocking part for material feeding.

[0012] Furthermore, the sealing mechanism includes a sealing member clamped by a second pressure plate on the outer wall of the other side of the housing and corresponding to the other side of the mounting port. The sealing member extends inward and flexibly abuts against the top of the rotating member.

[0013] Furthermore, it also includes an adjustment mechanism, which includes an adjustment member with its lower end inserted between the upper end of the first pressure plate and the outer wall of the housing; an adjustment shaft vertically rotatably disposed outside the housing and connected to the adjustment member; and an adjustment drive assembly for driving the adjustment shaft to rotate inward or outward. The material blocking mechanism also includes several threaded members that are threaded through the middle of the housing and the first pressure plate and are distributed laterally at intervals; and several threaded parts that are respectively limited and threaded to the inner and outer ends of the several threaded members. Each of the several threaded members is fitted with a first spring that is positioned between the threaded parts and the outer wall of the housing and the outer end of the housing. After the two adjustment shafts rotate inward, the lower end of one side of the adjustment member rotates outward and pushes the upper end of the first pressure plate outward, so that the lower end of the first pressure plate swings inward and presses the material blocking part inward under the elastic force of the several first springs.

[0014] Furthermore, the adjustment drive assembly includes a first link, a second link, and a third link that are rotatably connected in sequence. The first link is linked to the adjustment shaft. The third link is located above the first link and has a plurality of positioning holes spaced apart along the axial direction. The outer wall of the housing is provided with positioning pins corresponding to the positioning holes. A second spring is connected between the end of the first link away from the second link and the middle part of the second link. The adjustment member is U-shaped with the opening facing downward and is fixedly covered on the outer wall of the adjustment shaft.

[0015] Furthermore, a plurality of the pushers are arranged in a circular array on the outer wall of the rotating member, with the pushers in adjacent columns being staggered.

[0016] Furthermore, the cavity is provided with a stirring rod that extends to the left and right and is driven to rotate by the rotating drive device. Several first stirring plates with the left end higher than the right end and several second stirring plates with the left end lower than the right end are fixed on the outer walls of both sides of the stirring rod. Several first stirring plates and several second stirring plates on the same side are staggered and spaced apart in the left and right lateral direction. Several first stirring plates and several second stirring plates on both sides are staggered and spaced apart in the left and right lateral direction.

[0017] Furthermore, the rotating component is configured as a roller, with rotating seats fixed at both ends of the roller and rotatably mounted on the housing. The rotation drive device drives one of the rotating seats to rotate via a sprocket and a chain. The rotating component is equipped with an eccentric mechanism, which includes a driven shaft rotatably connected to the two rotating seats at both ends via bearings, and an eccentric wheel fixedly sleeved on the driven shaft and spaced apart from the two rotating seats. The rotating component is also equipped with a locking mechanism for locking the two rotating seats and the two ends of the driven shaft. When the locking mechanism locks the two ends of the driven shaft, the rotating component rotates and drives the driven shaft and the eccentric wheel to rotate, generating an eccentric force to cause the rotating component to vibrate.

[0018] Furthermore, the two rotating seats are recessed on opposite sides with rotating grooves. The two ends of the driven shaft are rotatably inserted into the rotating grooves through bearings. The side walls at both ends of the driven shaft are recessed with a plurality of limiting grooves at intervals. The inner wall of the rotating groove is recessed with a plurality of positioning grooves corresponding to the limiting grooves. The locking mechanism includes a plurality of locking pins adapted to slide in the plurality of limiting grooves, a plurality of third springs connecting the plurality of locking pins and limiting grooves, and a plurality of electromagnets disposed on the inner wall of the rotating seat and corresponding to the bottom of the plurality of positioning grooves. When the plurality of electromagnets are energized, they magnetically attract the plurality of locking pins to be inserted into the plurality of positioning grooves and circumferentially lock the plurality of positioning grooves and limiting grooves, thereby locking the driven shaft and the rotating seat. When the plurality of electromagnets are de-energized, the plurality of locking pins are reset by the tension of the plurality of third springs and disengage from the plurality of positioning grooves to unlock.

[0019] Furthermore, the receiving cavity is provided with a vibrating mechanism, which includes a plurality of rigid vibrating elements spaced apart along the axial direction of the rotating member. One end of each vibrating element is inserted and fixed inside the sealing member, and the other end forms a vibrating section extending to a gap between the sealing member and the sealing member. The vibrating sections are spaced apart above the rotating member, and the gaps between the vibrating sections form a screening gap. When the rotating member vibrates, the sealing member drives the vibrating elements to vibrate, thereby causing the vibrating sections to vibrate.

[0020] The beneficial effects of this utility model are:

[0021] 1. Through the setting of the baffle mechanism and several pushing parts, when the rotating part rotates to the point where the pushing parts open the baffle, several material discharge gaps are formed between the rotating part and the baffle. This allows the material discharge gaps to continuously open and close with the rotation of the rotating part during the application of de-icing agent. Furthermore, the pushing parts, rotating with the rotating part, can to a certain extent crush the de-icing agent entering the material discharge gaps, thus preventing the installation port from being blocked by de-icing agent and thus preventing material discharge. Even if the installation port is blocked by de-icing agent after the material discharge attachment has been stopped for a certain period, the rotating part can still drive the pushing parts to break up the agglomerated de-icing agent in the installation port and between the rotating part and the baffle, allowing the material discharge to continue. This ensures the efficiency and restart speed of the material discharge attachment, guaranteeing the effective application of the de-icing agent. Based on this, by setting up a blocking mechanism, when the rotating part rotates to the blocking part on several pushing parts, the de-icing agent will move towards the blocking part on one side with the rotational force of the rotating part, and will not easily leak out from the gap between the blocking part and the rotating part. This ensures that the de-icing agent can be stably discharged through the discharge gap, ensuring the feasibility and stability of the cooperation between the rotating part and the blocking part, and improving the discharge stability of the discharge attachment.

[0022] 2. By adding an adjustment mechanism and several first springs, the inward swing angle of the lower end of the first pressure plate can be adjusted by rotating the adjustment component to adjust the tightness of its pressing on the material blocking part. This, in turn, adjusts the degree of deformation of the material blocking part when several pushing components push it open, thereby adjusting the width of the material discharge gap formed between the rotating component and the material blocking part. This allows for the adjustment of the material discharge amount, enabling the material discharge attachment to adapt to different road surfaces and different snow accumulation levels to adjust the amount of de-icing agent spread, thus improving the adaptability of the material discharge attachment.

[0023] 3. By adding the first, second, and third connecting rods, the width of the material feeding gap can be adjusted by manually pulling the first connecting rod before the snow melting and spreading work is carried out. Then, the corresponding positioning hole is fitted onto the positioning pin and the pin is inserted to lock it. This reduces the adjustment drive cost and the overall manufacturing and working cost of the material feeding attachment while achieving adjustable material feeding gap width.

[0024] 4. When the rotating component drives several pushing components to rotate, the several rows of pushing components alternately squeeze and crush the de-icing agent falling to the top of the rotating component and in the material feeding gap, which improves the crushing effect, further avoids the situation of de-icing agent clumping and ineffective feeding, and further ensures the stability of feeding.

[0025] 5. The agglomerated de-icing agent in the containment cavity is stirred and broken up by the stirring action of several first and second stirring plates. The adjacent first and second stirring plates with opposite inclination angles can tumble and squeeze the de-icing agent in the containment cavity to improve the stirring and breaking effect.

[0026] 6. By adding an eccentric mechanism, after the feeding attachment has been working for a certain period of time and a certain amount of clumped de-icing agent has accumulated in the installation opening, the two ends of the driven shaft can be locked by the locking mechanism, causing the rotating part to rotate and drive the driven shaft and eccentric wheel to rotate, generating eccentric force, which in turn causes the rotating part to vibrate. This vibration breaks up the clumps of de-icing agent accumulated in the installation opening and on the top of the rotating part, preventing the clumps of de-icing agent from clogging the installation opening and making it difficult for the loose de-icing agent to pass through the feeding gap, thus preventing unstable feeding. It also prevents excessive accumulation of clumps of de-icing agent in the installation opening, which could block the installation opening and prevent feeding from the feeding gap. This further ensures the feeding stability and spreading effect of the feeding attachment during long-term operation.

[0027] 7. When it is necessary to vibrate the crushed material through the rotating part, the driven shaft ends can be quickly locked by the magnetic attraction of several electromagnets to several locking pins. When the vibration of the rotating part is not needed, the locking pins can be quickly reset and unlocked by the de-energization of several electromagnets and the elastic force of several third springs. This improves the locking efficiency and unlocking efficiency of the locking mechanism. At the same time, the electromagnets only need to be energized when the locking mechanism is locked, and the vibration time of the rotating part is only a few minutes. The electromagnets do not need to be energized when the locking mechanism is unlocked. Therefore, the power consumption of the locking mechanism can be greatly saved, the power cost of the material feeding attachment can be reduced, and the overall snow melting and spreading work cost can be reduced.

[0028] 8. By adding a vibrating material mechanism, during material feeding, loose de-icing agent can be directly fed through the screening gaps between several vibrating material sections, while clumped de-icing agent is blocked at the top of several vibrating material sections. This allows for screening and sorting of the de-icing agent fed to the installation port and the top of the rotating part before vibration. On this basis, when the rotating part vibrates, the sealing part drives several vibrating material sections to vibrate, so that several vibrating material sections directly break up the clumped de-icing agent that has been screened out and accumulated at the top. Thus, the vibration force of the rotating part is directly transmitted to the screened clumped de-icing agent through the sealing part and the vibrating material sections, without being weakened by the loose de-icing agent accumulated at the top of the rotating part. Through the coordination of the vibrating material mechanism and the vibration of the rotating part, the targeting of clumped de-icing agent is improved, and the vibration effect and efficiency are improved.

[0038] Example 1

[0039] Reference Figure 1-5 As shown, a feeding attachment for spreading snow melt includes:

[0040] A housing 1 with an installation port 12 at the bottom and a receiving cavity 11 inside the housing 1; the housing 1 is used to be mounted on a corresponding loading vehicle, and the receiving cavity 11 is used to contain de-icing agent;

[0041] Rotating component 2 rotates to correspond to the inner side of the mounting port 12 and is driven to rotate by the rotation drive device 3. The outer wall of the rotating component 2 is provided with a plurality of spaced pushers 21.

[0042] A baffle mechanism 4 is used to flexibly seal the other side of the mounting opening 12. Specifically, the baffle mechanism 4 includes a baffle member 41 that is clamped to one side of the outer wall of the housing 1 by a first pressure plate 42 and corresponds to one side of the mounting opening 12. The lower end of the baffle member 41 protrudes from the first pressure plate 42 to form a baffle portion 411 that flexibly abuts against the outer wall of the rotating member 2. The upper end of the baffle portion 411 abuts against the outer wall of the rotating member 2, and the lower end extends away from the rotating member 2. The baffle member 41 is made of an elastic material such as rubber.

[0043] The sealing mechanism 5 includes a sealing member 51 clamped by a second pressure plate 52 on the outer wall of the housing 1 on the other side and corresponding to the other side of the mounting opening 12. The sealing member 51 extends inward and flexibly abuts against the top of the rotating member 2. When the rotating member 2 rotates to the point where several pushing members 21 push open the material blocking part 411, several material feeding gaps are formed between the rotating member 2 and the material blocking part 411 for material feeding. Specifically, the sealing member 51 is made of an elastic material such as rubber.

[0044] The above structure, through the arrangement of the baffle mechanism 4 and several pushers 21, ensures that when the rotating member 2 rotates to the point where the pushers 21 push open the baffle part 411, several material discharge gaps are formed between the rotating member 2 and the baffle part 411. This allows the material discharge gaps to continuously open and close with the rotation of the rotating member 2 during the application of de-icing agent. Furthermore, the pushers 21, rotating with the rotating member 2, can to a certain extent crush the de-icing agent entering the material discharge gaps, thus preventing the installation port 12 from being blocked by the de-icing agent and preventing material from being discharged. Even if the installation port 12 is blocked by de-icing agent after the material discharge attachment has been stopped for a certain period, the rotating member 2 can still drive the pushers 21 to break up the de-icing agent clumps in the installation port 12 and between the rotating member 2 and the baffle plate, allowing the material discharge to continue. This ensures the efficiency and restart speed of the material discharge attachment, guaranteeing the effective application of the de-icing agent. Based on this, by setting the sealing mechanism 5, when the rotating part 2 rotates to push the sealing part 51 on several pushing parts 21, the de-icing agent will move towards the material blocking part 41 on one side with the rotational force of the rotating part 2, and will not easily leak out from the gap between the sealing part 51 and the rotating part 2, so as to ensure that the de-icing agent can be stably discharged through the discharge gap, and to ensure the feasibility and stability of the cooperation between the rotating part 2 and the material blocking part 41, thereby improving the discharge stability of the material feeding attachment.

[0045] To improve the adaptability of the feeding attachment, it also includes an adjustment mechanism 6. The adjustment mechanism 6 includes an adjustment member 61 with its lower end inserted between the upper end of the first pressure plate 42 and the outer wall of one side of the housing 1; an adjustment shaft 62 that is vertically rotatably disposed on the outer side of the housing 1 and connected to the adjustment member 61; and an adjustment drive assembly for driving the adjustment shaft 62 to rotate inward or outward. The material blocking mechanism 4 also includes several screwed members 43 that are threaded through the middle of the housing 1 and the first pressure plate 42 and are distributed laterally at intervals, respectively limiting the movement of the material. A plurality of screw fittings 44 are screwed to the inner and outer ends of a plurality of screw connectors 43. A first spring 45 is respectively fitted on the plurality of screw connectors 43 between the screw fittings 44 and the outer end of the housing 1. Specifically, the screw connectors 43 are bolts and the screw fittings 44 are nuts. After the two adjusting shafts 62 are rotated inward, the lower end of one side of the adjusting member 61 rotates outward and pushes the upper end of the first pressure plate 42, so that the lower end of the first pressure plate 42 swings inward and presses the stop part 411 under the elastic force of the plurality of first springs 45. By adding the adjustment mechanism 6 and several first springs 45, the inward swing angle of the lower end of the first pressure plate 42 can be adjusted by rotating the adjustment member 61 to adjust the tightness of its pressing on the material blocking part 411. This, in turn, adjusts the degree of deformation of the material blocking part 411 when several pushing members 21 push it open, thereby adjusting the width of the material discharge gap formed between the rotating member 2 and the material blocking part 411. This allows for the adjustment of the amount of material discharged, enabling the material discharge attachment to adapt to different road surfaces and different snow accumulation levels to adjust the amount of de-icing agent spread, thus improving the adaptability of the material discharge attachment.

[0046] To save costs, the adjustment drive assembly includes a first connecting rod 63, a second connecting rod 64, and a third connecting rod 65 that are rotatably connected in sequence. The first connecting rod 63 is linked to the adjustment shaft 62. The third connecting rod 65 is located above the first connecting rod 63 and has a plurality of axially spaced positioning holes 651. The outer wall of the housing 1 is provided with positioning pins 13 corresponding to the positioning holes 651. A second spring 66 is connected between the end of the first connecting rod 63 away from the second connecting rod 64 and the middle part of the second connecting rod 64. The adjustment member 61 is U-shaped with the opening facing downward and is fixedly covered on the outer wall of the adjustment shaft 62. By adding the first link 63, the second link 64, and the third link 65, the width of the material feeding gap can be adjusted by manually pulling the first link 63 before the snow melting and spreading work is carried out. Then, the corresponding positioning hole 651 is fitted onto the positioning pin 13 and the pin is inserted to lock it. This reduces the adjustment drive cost and the overall manufacturing and working cost of the material feeding attachment while achieving adjustable material feeding gap width.

[0047] To improve the crushing effect of the pushers 21 on the de-icing agent falling onto the top of the rotating member 2 and into the feeding gap, a plurality of pushers 21 are arranged in a circular array on the outer wall of the rotating member 2, with adjacent columns of pushers 21 staggered. Thus, when the rotating member 2 drives the pushers 21 to rotate, the staggered arrangement of the pushers 21 crushes the de-icing agent falling onto the top of the rotating member 2 and into the feeding gap, improving the crushing effect, further preventing the de-icing agent from clumping and resulting in ineffective feeding, and further ensuring feeding stability.

[0048] To reduce the probability of de-icing agent agglomeration in the receiving cavity 11, a stirring rod 14 extending laterally and driven to rotate by the rotary drive device 3 is provided inside the receiving cavity 11. Several first stirring plates 15 with their left ends higher than their right ends and several second stirring plates 16 with their left ends lower than their right ends are fixed to the outer walls of both sides of the stirring rod 14. The first stirring plates 15 and the second stirring plates 16 on the same side are staggered laterally, and the first stirring plates 15 and the second stirring plates 16 on both sides are also staggered laterally. Thus, the stirring action of the first stirring plates 15 and the second stirring plates 16 stirs and breaks up the agglomerated de-icing agent in the receiving cavity 11. Furthermore, adjacent first stirring plates 15 and second stirring plates 16 with opposite inclination angles can tumble and compress the de-icing agent in the receiving cavity 11, thereby improving the stirring and breaking effect.

[0049] Example 2

[0050] refer to Figure 5-9 The difference between this embodiment and Embodiment 1 is that:

[0051] To further reduce the risk of caking de-icing agent blocking the installation port 12 and the material discharge gap, the rotating component 2 is a roller. Rotating seats 22, rotatably mounted on both ends of the roller and rotatably connected to the housing 1, are fixed at both ends. The rotation drive device 3 drives one of the rotating seats 22 to rotate via a sprocket and chain. An eccentric mechanism 7 is provided inside the rotating component 2. The eccentric mechanism 7 includes a driven shaft 71 rotatably connected to the two rotating seats 22 via bearings 711 at both ends, and an eccentric wheel 72 fixedly sleeved on the driven shaft 71 and spaced apart from the two rotating seats 22. The rotating component 2 is also provided with a locking mechanism 8 for locking the two rotating seats 22 and the two ends of the driven rotating shaft 71. When the locking mechanism 8 locks the two ends of the driven rotating shaft 71, the rotating component 2 rotates and drives the driven rotating shaft 71 and the eccentric wheel 72 to rotate, generating an eccentric force to drive the rotating component 2 to vibrate. Thus, the vibration of the rotating component 2 can vibrate the de-icing agent on its top. In actual use, the rotation of the rotating drive device 3 can be increased to increase the vibration frequency and improve the vibrating effect. The vibration time only needs to be a few minutes.

[0052] The above-mentioned structure, through the addition of the eccentric mechanism 7, allows the driven shaft 71 to be locked by the locking mechanism 8 after the feeding attachment has been working for a certain period of time and a certain amount of clumped de-icing agent has accumulated in the installation port 12. This causes the rotating part 2 to rotate and drive the driven shaft 71 and the eccentric wheel 72 to rotate, generating an eccentric force. This force causes the rotating part 2 to vibrate, thereby breaking up the clumps of de-icing agent accumulated in the installation port 12 and on the top of the rotating part 2. This prevents the clumps of de-icing agent from clogging the installation port 12, making it difficult for the loose de-icing agent to pass through the feeding gap and causing unstable feeding. It also prevents excessive accumulation of clumps of de-icing agent in the installation port 12, which could block the feeding gap and prevent feeding. This further ensures the feeding stability and spreading effect of the feeding attachment during long-term operation.

[0053] To improve the locking and unlocking efficiency of the locking mechanism 8, the two rotating seats 22 are recessed on opposite sides with rotating grooves 221. The two ends of the driven shaft 71 are rotatably inserted into the rotating grooves 221 via bearings 711. The side walls at both ends of the driven shaft 71 are recessed with a plurality of limiting grooves 712 at intervals around the circumference. The inner wall of the rotating groove 221 is recessed with a plurality of positioning grooves 222 corresponding to the limiting grooves 712. The locking mechanism 8 includes a plurality of locking pins 81 adapted to slide within the plurality of limiting grooves 712, and connecting the plurality of locking pins. Several third springs 82 of 81 and limiting groove 712, and several electromagnets 83 disposed on the inner wall of the rotating seat 22 and corresponding to the bottom of several positioning grooves 222; when several electromagnets 83 are energized, they magnetically attract several locking pins 81 to lock into several positioning grooves 222 and the limiting groove 712 circumferentially, thereby locking the driven rotating shaft 71 and the rotating seat 22; when several electromagnets 83 are de-energized, several locking pins 81 are reset by the pulling force of several third springs 82 and disengage from several positioning grooves 222 to unlock. Therefore, when the rotating part 2 needs to vibrate the crushed material, the magnetic attraction of several electromagnets 83 to several locking pins 81 can quickly lock both ends of the driven rotating shaft 71. When the rotating part 2 does not need to vibrate, the electromagnets 83 can be de-energized and lose their magnetic attraction, and the elastic force of several third springs 82 can cause the locking pins 81 to quickly reset and unlock, thereby improving the locking efficiency and unlocking efficiency of the locking mechanism 8. At the same time, the electromagnets 83 only need to be energized when the locking mechanism 8 is locked, and the vibration time of the rotating part 2 is only a few minutes. When the locking mechanism 8 is unlocked, the electromagnets 83 do not need to be energized. Therefore, the power consumption of the locking mechanism 8 can be greatly saved, the power cost of the material feeding attachment can be reduced, and the overall snow melting and spreading work cost can be reduced.

[0054] Because a large amount of loose and clumped de-icing agent mixes and accumulates at the top of the rotating part 2, the vibration effect of the rotating part 2 is weakened by the blockage and consumption of the loose de-icing agent, making it difficult to target the clumped de-icing agent. Therefore, in order to improve the vibration effect and efficiency, a vibration mechanism 9 is provided in the receiving cavity 11. The vibration mechanism 9 includes several rigid vibration elements 91 spaced apart along the axial direction of the rotating part 2. One end of each vibration element 91 is inserted and fixed in the sealing member 51, and the other end forms a vibration section 911 extending to a gap with the baffle member 41. The vibration sections 911 are spaced above the rotating part 2, and the gaps between the vibration sections 911 form a screening gap 92. Specifically, the two ends of the vibration elements 91 are rounded. Thus, by adding the vibration mechanism 9, when feeding material during the feeding gap, Loose de-icing agent can be directly fed through the screening gap 92 between several vibrating sections 911, while clumped de-icing agent is blocked at the top of several vibrating sections 911. This allows the de-icing agent fed to the installation port 12 and the top of the rotating part 2 to be screened and divided before vibration. On this basis, when the rotating part 2 vibrates, the sealing member 51 drives several vibrating members 91 to vibrate, so that several vibrating sections 911 directly break up the clumped de-icing agent that has been screened out and accumulated at the top. Thus, the vibration force of the rotating part 2 is directly transmitted to the screened clumped de-icing agent through the sealing member 51 and the vibrating members 91, without being weakened by the loose de-icing agent accumulated at the top of the rotating part 2. Through the cooperation of the vibrating mechanism 9 and the vibration of the rotating part 2, the targeting of the clumped de-icing agent is improved, and the vibration effect and efficiency are improved.
